y tainer, for the material to be sliced, in one direction or in an opposite direction.

A further object of the invention is to de- -vise a novel slicing machine of the charac- "ter' stated wherein the article container has Van open bottom and travels over a fixed knife having cutting edges at opposite sides and ywherein the articles in the container are supported by a belt moving in the same direction as the article container to support the articles therein.

A further object of the invention is to de- Vvise novel means for preventing the cut material accumulating at the cutting edges of `the knife, and, as illustrated, this means is in the form of bars connected with endless edgesv of the knife.

Vith the above and other objects in view, Vmy invention comprehends a novel slicing machine wherein a reciprocatory motion is imparted to an article container which travels across a fixed knife having cutting edges on opposite sides and wherein the bottom of the article container is formed by traveling belts which support the articles to be sliced Vwhich are in the article container.

It'further comprehends a novel construction and arrangement of cutting mechanism, an article container, and endless belts which travely in the same direction and preferably at the same speed as the article container andV which are provided with means for'wiping the cutting edges of the knife.

Other novel features of construction and advantage will hereinafter more clearly appear'in the detailed description and the appended claims.

For the purpose of illustrating the invention I have shown-in the accompanying i drawings a typicalembodiment of it, which,

. aprons traveling in proximity to the cutting Serial No. 497,169.

in practice, will give reliable and satisfactory results. It is, however, to be understood that this embodiment is typical only and that the various instrumentalities of which my invention consists can be variously arranged and 5 organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Figure 1 is a top plan view of a slicing ma- 'l chine embodying my invention.

Figure 2 is a side elevation of a portion of the machine.

Figure 3 is a section on line 3-3 of Fig-1 y ure 1.

Similar numerals of reference indicate cor responding parts.

Referring to the drawings 1 designates a supporting frame of any rdesired character, which, as illustrated, consists of standards 2 connected with end bars to which are connected the side bars 4 there- 'by forming a rectangular framework. The

side hars 4 are provided with grooves 5 in their inner sides to receive the rollers 6 car' ried by the article container 7. This article container 7 may have any desired contour in 'cross section, but, as illustrated, is rectanguor the other of the cutting edges of the stationary knife 8. The article container has connected with it, in any desired manner, a

rack 10 which meshes with the pinions 11 carried by shafts 12. The Shafts 12 are provided with rollers 13 around one of which passes an endless belt 14 and around the other of which passes an endless belt 15. The belt '14 also passes around a roller lo jeurnalled in the machine frame and in e similar man ner the belt 15 passes around a roller 17 ourlnalled in the machine frame. rIhis provides two endless belts which are driven by the revolution of their respective shafts 12 as I the article container 7 moves forwardly or rearwardly. The belt 14 is provided with an upwardly extending rib 18 and in a similar manner the belt 15 is provided with an upwardly extending rib 19.y rl"hese ribs 18 and 19 serve to wipe the juxtaposed edges of the stationary knife 8 and prevent any accumulation of the cut`V material thereon.

The article container 7 may be. reciprocated in any desired manner. For the pury,

pose of illustration, I have shown an electric motor 20 provided with avdisc'r 21to .which is eccentrically connected one end of a connecting rod 22, the opposite end of which is connected at 23, to the racklO. Of course, this driving connection might be connected to either ofthe shafts ofthe rollers 16 'or `17, or any other desired manner to the article latter. Y

In the operationof my device, it will be .container 7 kto'eifect the -reciprocations of the apparent that'whenthe motor is started it will e-Eect the reciprocatorymovement of the rack 10 and the article container 7 to which it is connected so that the article container will pass to and fro over the stationaryV knife 8.

'As the rack 10 is in mesh with the pinions 1l, Eit Ywill cause the` revolution of the shafts 12, thereby driving their rollers 13 and the end- AVless belts 14-and'15.

n Win aus' be @im that if theme01@ Container 7 is filled with material to be cutthe material will be cut as it passes over-the stationary knife .8 in one direction, by one cutting edge of the knife, and, as it moves in the .opposite direction, the material will be cut fthesamespeed as the articlecontainer. As

.the article container moves over the stationary knife`v 8 it will be apparent that the endless belt on the opposite side acts. in the same l way to .forma closedbottom for the article container.V

In .each forwardr or reverse movement of an endless belt 14 Aor 15, it will be .apparent that theribs 18and 19 have a wiping contactwith-r the cutting edges 9 .of the stationary knife 8 so that these cutting edges. are always. retained Vin fproperf cutting condition. The cut material passes downwardly between the belts and the .stationary knife. into a receptaCIe, vnot shown, placedA beneath such opening-*to receive. the materialwhich has Y beensliced lor cut.

I twill nowy be apparent that I have devised anew and useful slicing machinewhich effect the reci embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice statisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacri- [icing any of its advantages. v

Having thus described my invention what I claim las new and desire to secure Vby Letters Patent, is

1. In a slicing machine, a frame, an article container slidably mounted therein for reciprocatory movement and having its bottom open, a pair of endless belts mounted in said frame over. which said article container reciprocates, a fixed knife having cutting edges at opposite sides positioned'between the juxtaposed ends ofisaid belts, yand-means toy effect the reciprocation of said article container.

2. n In a slicing machine, a reciprocatory article, container,having,anI open bottom, a stationary knife havin@ at opposite sidescutting vedges and Vover which saidcontainerrecipro- Cates, endless belts havingoneend juxtaposed in proximity to said knife to` fOrmLduring .thejmovement of the articleljcontainer, a

closed bottom therefor, said belts being interconnected to move in thlensamedirection, and means to effectthe reciprocationof said Aarticle containerfover said belts and said .sta-

tionary knife.

3. In ay slicing machine,aframe, a fixed" knife, anarticle container having an open bottom, and means to effect the reciprocatory movement of saidL article container and to cause each of said belts tolmove in the same direction` and at thevsame speed as the direction and speed of movement of the article container. Y l

4. In a slicing machine, a frame, aciixed knife therein having cutting edges at opposite sides, rollers carriedby said fra1ne,endless belts cooperating withsaid rollers, the rollers at one end of the belts, being juxtaposed tothe stationary knife and provided with shafts, an article container4 guidedin saidframe. to travel across said stationary knife, means to operatively connect said article container with said shafts whereby the latter willbe driven in uniSOIlvWth and in the same directionas the directionof movement of the article container, and meansto s procatory movementof said articlecontainer. l V

Y 5. In` aslicingn machine, afframe, a fixed knife having cutting edges at opposite sides carried by said frame intermediate its ends, an article container having an open bottom guided in said frame to travel over said knife, shafts j ournalled in said frame, endless belts driven by said shafts to close the bottom of said article container during its reciprocatory movement, a rack and pinion connection With said belts, an article container to cause them to move in unison with each other, and means to effect the travel of said belts and thereby the reciprocatory movement of the article container.
